We are a Colombian women's clothing brand founded in 2019 in California, United States. We began developing seamless activewear, which we distribute through Amazon and our website. In 2021, we launched our best-selling products in the United States and Colombia, standing out as the first to offer seamless activewear thicker than standard seamless, similar to denim, which has been key to building customer loyalty.

We currently operate from Medellín with sales exclusively online, but we plan to open a showroom by the end of 2025 , understanding the importance of garment try-on capabilities. Although Stri40 started in the sportswear sector, we are now focusing on creating formal and casual dresses for women ages 20 to 45.

Since 2023, we've been developing an exciting project called Stri40 Atelier. Welcome to our world, where details are key and dresses become essential pieces in the wardrobe of every woman who seeks to highlight her femininity. Their versatility allows them to be worn on a variety of occasions, paired with elegant heels or comfortable sneakers, without sacrificing style. Our passion for dresses and their fine details has led us to create this line, which we hope you enjoy as much as we do.
